bug#5694: 23.1; Input lines are echoed in shell-mode after invoking gnuplot

[Charlie Kravetz]

This was reported to Ubuntu Launchpad as https://bugs.launchpad.net/bugs/533270.

1. start emacs using emacs -q
2. In emacs, type M-x shell 
3. In shell-mode, type
   gnuplot RET
to run gunplot
4. Type C-d to quit gnuplot
5. Type any command, for example,
   ls
in shell-mode. The command will echo as the first line of the results.
The command entered should not be echoed. It does not echo if gnuplot is not started and stopped first.

When gnuplot is invoked in ansi-term mode, the echoing does not occur.

I cannot reproduce that.  In any case, this looks rather like a bug in
gnuplot clobbering the terminal (echo) settings.

This seems unlikely to be an Emacs bug, so I'm closing this bug report.
